A C++ application framework for Xfce and GTK+ The Xfce Foundation Classes is a set of integrated C++ classes for developing Xfce applications on UNIX-like operating systems such as Linux. The classes combine the power of GTK+ and the power of C++ into a state-of-the-art application development framework for the Xfce Desktop Environment. The classes judiciously use C++ language features to avoid layering on too much extra C++ complexity. The API is easy to understand and use, and should feel immediately familiar to most GTK+ programmers. The Xfce Foundation Classes is part of the Xfce project, and like Xfce it\'s lightweight, fast and easy to use. Currently there are three modules, the core object system and utility library (libXFCcore), the user interface library (libXFCui) and the Glade XML parser (libXFCglade).
